Ingredients
For the Casserole:
· 12 oz (340g) short pasta (Rotini, penne, or shells work best)
· 2 tablespoons olive oil or butter
· 1 medium yellow onion, finely diced
· 1 red bell pepper, diced
· 1 green bell pepper, diced
· 3 cloves garlic, minced
· 3 cups cooked shredded chicken (Rotisserie chicken is perfect here!)
· 1 (10.5 oz) can cream of chicken soup (or cream of mushroom)
· 1 cup sour cream (or plain Greek yogurt for a lighter option)
· 1/2 cup chicken broth (to adjust consistency)
· 1 teaspoon paprika (Smoked paprika adds great depth)
· 1/2 teaspoon garlic powder
· Salt and black pepper, to taste
· 2 cups shredded cheddar cheese, divided
· 1 cup shredded Monterey Jack or mozzarella cheese, divided
For the Topping:
· 1/4 cup fresh parsley, chopped (for garnish, as seen in the photo)
· Optional: 1/2 cup crushed crackers or panko breadcrumbs mixed with 1 tbsp melted butter for a crispy top.
Instructions
Step 1: Cook the Pasta
Preheat your oven to 375°F (190°C). Grease a 9×13-inch glass baking dish (like the one in the photo) with cooking spray. Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente (slightly firm, about 1-2 minutes less than the recommended time, as it will continue cooking in the oven). Drain and set aside.
Step 2: Sauté the Vegetables
While the pasta cooks, heat the olive oil or butter in a large skillet or Dutch oven over medium heat. Add the diced onion and bell peppers. Cook, stirring occasionally, until they begin to soften (about 5-6 minutes). Add the minced garlic and cook for another minute until fragrant.
Step 3: Make the Creamy Sauce
Turn the heat down to low. Stir in the cream of chicken soup, sour cream, and chicken broth. Add the paprika, garlic powder, salt, and pepper. Stir until everything is smooth and combined.
Step 4: Combine Everything
Fold the shredded chicken and the cooked, drained pasta into the sauce mixture. Stir until all the pasta and chicken are well coated. Remove the skillet from the heat and stir in 1.5 cups of the shredded cheddar and 1 cup of the Monterey Jack cheese until melted and incorporated into the mixture.
Step 5: Assemble and Bake
Pour the entire mixture into your prepared 9×13 baking dish. Spread it out evenly. Sprinkle the remaining 1/2 cup of cheddar cheese over the top (add the optional breadcrumb topping here if you want a crispy crust).
Step 6: The Final Bake
Place the dish in the preheated oven and bake for 20-25 minutes, or until the cheese is melted, bubbling, and starting to turn golden brown around the edges.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it rest for 5 minutes—this allows the sauce to settle, making it easier to serve. Garnish generously with the fresh chopped parsley (as shown in the picture) and serve warm.
💡 Chef’s Tips for the Perfect Bake:
· Don’t Overcook the Pasta: Mushy pasta ruins a casserole. Always cook it al dente, as the oven will soften it further.
· Customize It: Feel free to swap the bell peppers for mushrooms, zucchini, or spinach. (If using spinach, add it in the last minute of sautéing).
· Make it Spicy: Add a pinch of crushed red pepper flakes or a diced jalapeño to the vegetable mix for a kick of heat.
· Make Ahead: You can assemble this casserole up to 24 hours in advance. Cover it with foil and refrigerate. When ready to bake, add about 10-15 minutes to the baking time and remove the foil for the last 10 minutes
